The present invention relates to an apparatus for controlling a low voltage DC-DC converter (LDC) of an eco-friendly vehicle, and a method thereof. The purpose of the present invention is to provide an apparatus for controlling an LDC of an eco-friendly vehicle, which improves fuel efficiency of the eco-friendly vehicle by operating the LDC that supplies current to an electric field load of the eco-friendly vehicle in a section having optimal energy conversion efficiency, and to a method thereof. To this end, the apparatus for controlling an LDC of an eco-friendly vehicle comprises: a storage unit for storing an output current amount (hereinafter, referred to as a reference current amount) having minimum energy conversion loss by an LDC; a required current amount detecting unit for detecting a current amount required from an electric vehicle load in an eco-friendly vehicle; and a control unit for controlling the LDC to output the reference current amount if the required current amount detected by the required current amount detecting unit is less than the reference current amount, and to output the required current amount if the required current amount is equal to or more than the reference current amount.

    본 발명은 친환경 차량의 LDC 제어 장치 및 그 방법에 관한 것으로, 친환경 차량의 전장부하(Electric field load)에 전류를 공급하는 LDC(Low voltage DC-DC Converter)를 최적의 에너지 변환 효율을 갖는 구간에서 가동시켜 친환경 차량의 연비를 향상시키는 친환경 차량의 LDC 제어 장치 및 그 방법을 제공하고자 한다. 이를 위하여, 본 발명은 친환경 차량의 LDC 제어 장치에 있어서, LDC(Low voltage DC-DC Converter)가 최소의 에너지 변환 손실을 가지는 출력 전류량(이하, 기준 전류량)을 저장하는 저장부; 친환경 차량 내 전장부하에서 요구하는 전류량을 검출하는 요구 전류량 검출부; 및 상기 요구 전류량 검출부에 의해 검출된 요구 전류량이 기준 전류량을 미만이면 기준 전류량을 출력하도록 LDC를 제어하고, 기준 전류량 이상이면 요구 전류량을 출력하도록 LDC를 제어하는 제어부를 포함한다.
